Conspiracy theorists often worry about plots to take over the world. I think they should add WSPR to their list of worrisome schemes. Just look at the above map. That represents just 24 hours of activity on only one band (30 meters).

Joe Taylor, K1JT, reports that on November 21, the WSPR system for the first time recorded over 100,000 reports in a 24 hour period. There are now more than 14 million reports logged in the WSPR system. That's a lot of signal reports!

I decided to check my own numbers: In a 15 hour period on December 3, my 20 mW HB DSB WSPR signal was picked up and reported 416 times. 18 different stations detected my signal and reported on the reception. My best DX was W3HH in Florida -- his rig decoded my sigs 4 times.
